It is well known that power saving is one of the most important issues for mobile device in accessing network services. The efficient conservation of energy for longer operation times of a mobile station is vital to the success of various mobile applications. This paper proposes a systematic approach to allocate radio resources in Long-Term Evolution Advanced (LTE-A) network by considering the channel condition and QoS requirements, while the power saving is a centric issue during the scheduling process. The proposed scheme includes the selection of component carriers (CC) and the allocation of radio resource to satisfy the QoS demands while minimize the power consumption of user equipment (UE). Additionally, exhaustive simulations were performed to examine the performance of the proposed scheme. Both http and video streaming traffic models were applied during the simulations. The experimental results show that the proposed scheme achieves better performance when compared to the other scheme.
